From the beginning of human existence, individuals have developed their abilities to achieve a specific goal. A conscious and purposeful approach to the realization of intentional activities is characterized as a method. Achieving a goal requires the proper arrangement of all elements and resources, aimed at intellectually comprehending objectives that are realized through practical action. For this reason, activities aimed at achieving a goal must be clearly defined and subsequent actions by individuals or specific interest groups must be carried out based on established norms and principles. A scientific abstract method is concretized through practical outcomes, which are characterized by human activity. The general characterization of a method is also updated in the ecclesiastical and canonical context. This implies a specific requirement for a method in relation to missionary activity, which in this paper focuses on the methodological guidance and actions in proclaiming the Good News by the Thessalonian brothers, Saints Cyril and Methodius.
